Hager JF443BS Isolator Incomer Kit 3 Pole 400A

Hager JF443BS: 400A 3 Pole Isolator Incomer Kit with protective cover, designed as the main isolation point for high-current distribution board installations.

Safety & Reliability

The JF443BS acts as the main switch for your distribution board, giving installers a single, reliable point to isolate the full incoming supply before working downstream. The integrated cover shields live parts from accidental contact, reducing risk on site during maintenance or fault-finding.

Installation & Compliance

An M12 lug terminal accepts heavy-gauge incoming cable, so the kit is sized for the demands of larger commercial and industrial supplies rated up to 400A. As part of the wider Hager electrical range, it is built to integrate directly with Hager distribution board systems, including boards fitted with RCBOs and AFDD protection, keeping the whole installation from one manufacturer for straightforward specification and sign-off.

Durable Construction

A robust plastic housing insulates the switch assembly and resists the knocks of a busy plant room or riser cupboard. The 3 pole configuration covers full three-phase isolation in a single compact unit, saving panel space compared to separate single-pole switching.
